Abstract

Provided is a permanent magnet variable transmission magnetic drum. The non-contact permanent magnet variable transmission magnetic drum aims to solve the problems that a traditional transmission gear box is complex in structure, and meshed and contacted transmission between gears generates noise, needs grease lubrication and is high in abrasion fault rate. The permanent magnet variable transmission magnetic drum is composed of a driving transmission shaft permanent magnet disc, a driven shaft permanent magnet disc and a fixed soft iron magnet disc, one or more pairs of permanent magnets are mounted on a flange plate, rare earth materials such as RbFeB, AlNiCo and SmCo strong magnetic materials can be selected as permanent magnet materials, and remanence-free soft iron and remanence-free ferrite can be selected as the magnet materials of the soft iron magnetic disc. The permanent magnet variable transmission magnetic drum is adopted to replace the complex transmission gear box, and the permanent magnet variable transmission magnetic drum can be widely applied to speed increasing devices of wind power generation, computers, control and driving devices for robots, automatic production line equipment and petrochemical equipment.

Description

Permanent-magnet variable-speed transmission magnetic drum

Technical field

The present invention relates to modern mechanical drive technology field, particularly a kind of permanent-magnet variable-speed transmission magnetic drum.

Background technique

In the seventies in last century to the eighties, I am engaged in pulsation electromagnetic suspension creative research, and this technology is used for to gyropilot aspect, naval vessel and independent navigation field, touched in a large number the device of permanent magnet in Tianjin, spend several years and found that again permanent magnet has indispensable purposes in mechanical transmission transmission technology field, in the machinery of transmission, gear is the indispensable basic element of character of gear, because gear is by the engagement driving between tooth and tooth, in the operation process of gear, its wearing and tearing easily cause mechanical failure, particularly in the middle generation noise pollution that runs up, traditional solution is to add lubricant oil, environment has been polluted again in the leakage of result lubricant oil, we observe gear is wearing and tearing and the noise that contact transmission causes in the obvious drawback of transmission process, we have reason to imagine so completely, create a kind of magnetic induction kind of drive that does not adopt contact without gear, its gear wear and noise have just been eliminated naturally, experiment, just can prove simply from one, we are by a compass, be placed on above desk, bring again a magnetic rod and be placed on the side in compass on desk, horizontally rotate again bar magnet, when we rotate permanent magnet one week, compass is also followed and is rotated 1 week, we bring 4 magnetic rods again, on the cross that adopts copper wire intersection binding hard paper to be cut into, form two pairs of magnetic poles, cross is put on the table and horizontally rotated cross 2 weeks with hand, found that compass has on the table rotated 2 weeks, repeat to do this experiment of rotation, its result is all that cross changes by 1 to 2 speedup transmission with compass, thus, between this object and object, do not produce the magnetic induction gear contacting and occur, be called magnetic induction gear effect.

Summary of the invention

The present invention discloses a kind of permanent-magnet variable-speed transmission drum, it is by driving shaft permanent magnetic disk, the critical piece compositions such as middle fixing soft iron disk and driven shaft permanent magnetic disk, 6 pairs of 12 strong-magnetic-field permanent-magnet iron of symmetrical installation on driving shaft permanent magnetic disk, and the magnetic pole of every adjacent magnets staggers each other, a pair of permanent magnet is installed on driven shaft permanent magnetic disk, in the time that driving shaft drives driven shaft to rotate, must be through the fixing soft iron disk coupling in a centre between its two transmissions permanent magnetic disk, and a pair of two soft magnetic bodies are installed on floppy disk, one side by from driving shaft disk axis to close fixing floppy disk, then driving shaft disk is rotated a circle, adopt the variation of magnet polarity tester soft magnetic bodies magnetic pole in the another side test floppy disk of floppy disk, the polarity that found that every soft magnetic bodies has produced 12 variations, then remove magnet polarity testing instrument, change driven shaft permanent magnetic disk whirligig near fixing floppy disk, driving shaft disk is rotated a circle, result driven shaft permanent magnetic disk has rotated 6 weeks, gear ratio is 1 to 6, determine thus the invention success of permanent-magnet variable-speed transmission magnetic drum.

Embodiment

The specific embodiment of the present invention, permanent magnet material of the present invention can select ultrastrong magnetic field rare earth material as rubidium iron boron, aluminium nickel cobalt, SmCo and high remanent magnetism ferrite; Soft magnet material can be selected without remanent magnetism material as: soft iron, without remanent magnetism ferrite.Manufacture the body material of gear magnetic drum as aluminum alloy and all nonmagnetic alloys, nonmetallic ring epoxy resins, plastics, polymer plastic and nanometer material, transmission disk topography is flange plate structure, and the profile of fixing soft iron disk is bearing block structure.

In the slewing range of 10 times, select one-level gear magnetic drum, more transmission ratio adopts Multi-stage speed-changing drive magnetic drum, determine permanent magnet magnetic field strength according to the size of transmission power, this variable speed drive is non-contact permanent magnet induction transmission device, unlubricated, noise free, less trouble, can be widely used in national defence marine machinery gear, the transmission of Aero-Space mechanical speed change, Petro-Chemical Machinery gear, new energy wind-driven generator and substitute traditional step-up gear.

The present invention's new technical field that extensively range applications is wanted in urgent needs such as industry automatic control, computer machine people, National Laboratory, modernization industry automatic lines.

This technological invention good effect has changed the gear graduation kind of drive of centuries, without lubricated, noise free with there is no mechanical wear.
